ah yes. backward. you have experience in that don't you?

In semis we do that all the time..its called skip shifing.
But it should go begin in 2nd skip 3rd shif mid rpm into 5th. from 4th

Ah, semis. It almost sounds like they're in the same gear after a shift.
Kind of like shifting a 10-15-18-21-speed bicycle, I suppose. You won't
want to run up through every gear all the time, just lose precious
momentum doing that.

I've always heard it called "Short Shifting". Used in racing, like the old
Indy cars, to conserve fuel.

This is ture but if you want to save gas with a manual, you do not
want to accelrate quickly or skip 4th. If anything, you want to get
out of 1st and second quickly without taching it out. Especailly
first. Do not slip clutch much either

Airplanes do it mainly to maintain peak HP RPM while accelerating and
climbing out as air desinty and speed changes. When you go for max
economy on a piston powered airplane with a constant speed prop you
actually reduce prop RPM too along with manifold pressure. (take a
bigger bite at a lower RPM) because the prop consumes power slicing
through the air too and in a econ cruise you can save fuel by reducing
prop RPM.

Your vehicle`s RPM`s are lower the higher the gear your in.
The lower the RPM`s means your engine isn`t working as hard. ( Just don`t
take off in 5th gear ) LoL

Accelerate gently and shift up as soon as the truck will pull in the
next higher gear.

Don't some Vipers have Skip Shift? The transmission shifts from first to
fourth at low throttle to save gas.

My Z06 had it as well. Some deal for the epa mileage thing. It is a real
pia, but very easy to eliminate. The first mod everybody does.

huh...never noticed...of course the 5 or 6 times i had the opportunity to
drive a viper i wasn't babying it LOL. guess I'm lucky the law didn't come
after me with the way i pushed the throttle.
